I have 2 computers and I set up a database in phpMyamin (Database 'Blah') with one computer and did some work in it, but then I was on my other computer and wanted to work on that same database (Database 'Blah') with that computer. Is there a way to do this?

I want to be able to work on that database "Blah" from the other computer as well.

Ok, you want access a database on computer A from a PHP script on computer B?

--> On computer A you must have a user in MySQL with access rights from everywhere. You can create such user with e.g. phpMyAdmin on computer A. Got to "Privileges" --> "Add new user" and And choose "Any Host" (%) for this user. (Or change a user you already have)

On computer B you use this user in your PHP script and as hostname you use the computer name or ip from computer A.

Well, on computer A, I set up the user with 'any host' as suggested, yet "practically", I'm not sure what exactly to do next on the other computer. I mean, when I go to the other computer, what 'specifically' do I do then? It's as if that computer has never heard of such a database? Am I supposed to log in or something?
